Key Findings
- Selank (300 µg/kg, intraperitoneal) boosted sensory attention 2–3× and learning capacity 1.5× in adult rats that experienced prenatal hypoxia.
- The peptide normalized exploratory behavior in open‑field and hole‑board tests.
- Serotonergic and noradrenergic brain activity levels were restored toward normal after Selank treatment.
Practical Outcomes
- The study suggests Selank might help recover cognitive function and neurotransmitter balance after early‑life oxygen deprivation, but it’s limited to an animal model with a high, injectable dose. For biohackers, it provides a modest hint that Selank could have neuro‑protective or cognitive‑enhancing properties, yet no direct human protocol or dosage can be derived from this data.
Summary
In a rat study, giving the peptide Selank after the animals were exposed to low oxygen before birth helped improve their attention, learning, and balanced brain chemicals like serotonin and norepinephrine. The drug seemed to reverse some long‑term brain effects caused by prenatal hypoxia.
Abstract
The effects of Selank synthetic analog of Tuftsin, representing the heptapeptide forming Thr-Lys-Pro-Arg-Pro-Gly-Pro, on behavior and serotonin/noradrenalin concentrations in brain were investigated in adult rats exposed to hypoxia during 14-16 days of gestation. It was revealed that injection of Selank (300 mkg/kg, i/p) increased 2--3-fold (p < 0.01) the sensory attention, facilitated 1.5-fold the learning capacity (p < 0.01), normalized exploratory activity in the open field and hole board, and recovered the balance of serotonergic and noradrenergic brain system activity. The data obtained demonstrate the possibility of Selank to compensate for long-lasting negative effects of antenatal hypoxia on integrative brain activity and brain monoamine level.
